The invention relates to an antenna arrangement (1) comprising at least one first antenna (2) which is designed to be connected to at least one second antenna (3) via a radio channel, at least one apparatus for detecting or predicting a movement of the first antenna (2) and/or of the second antenna (3) and for determining a spatial movement trajectory (5) of the first antenna (2) relative to the second antenna (3), wherein at least one calculation unit (6) is provided and is designed, if the first antenna (2) moves, to calculate a spatial counter-movement trajectory (7) which runs substantially opposite to the movement trajectory (5) in space and/or, if the second antenna (3) moves, to calculate a spatial co-movement trajectory which runs in a substantially identical manner to the movement trajectory (5) in space, an adaptation apparatus (8) is provided and is configured to adapt the spatial radiation characteristic of the first antenna (2) during the movement along the counter-movement trajectory (7) and/or the co-movement trajectory in such a manner that the properties of the radio channel remain substantially unchanged despite the movement.

When devices are moved, this causes the antenna to move to a different position, which in turn causes the wireless communication channel to change. With this invention the channel is kept static by performing a counter-movement with the antenna, to keep the antenna at the same position relative to other stations. A laboratory prototype was built for phones in cellular networks (5G and beyond). Measurement results confirm that channels can be kept static with this invention. The invention contains the method to keep the channel static under platform movement, as well as several devices to perform the counter-movement. By adding means to the base antenna for detecting the trajectory of the the moving antenna, the counter-movement previously performed by the antenna on the moving object can instead be performed at the base station. Devices such as cell phones, where the antena might not be able to perform the counter-movement due to size limitations, can offload the movement to another, larger antenna.
